$2-9$ Irry Pre Vaa The CT Computers Corporation is considering whether to begin offering customers the option to have their old personal computers $($PCs$)$ recycled when they purchase new systems. The recycling system would require CT Computers to invest $$600,000$ in the grinders and magnets used in the recycling process. The company estimates that for each system it recycles, it would generate $$1\mathrm{.}50$ in incremental revenues from the sale of scrap metal and plastics. The machinery has a five$-$year useful life and will be depreciated using straight$-$line depreciation toward a zero salvage value. CT Computers estimates that in the first year of the recycling investment, it could recycle $100,000$ PCs and that this number will grow by $25\%$ per year over the remaining four$-$year life of the recycling equipment. CT Computers uses a $15\%$ discount rate to analyze capital expenditures and pays taxes equal to $30\%.$ a$.$ What are the project cash flows? You can assume that the recycled PCs cost CT Computers nothing. b$.$ Calculate the NPV and IRR for the recycling investment opportunity. Is the investment a good one based on these cash flow estimates? c$.$ Is the investment still a good one if only $75,000$ units are recycled in the first year? d$.$ Redo your analysis for a scenario in which CT Computers incurs a cost of $$0\mathrm{.}20$ per unit to dispose of the toxic elements from the recycled computers. What is your recommendation under these circumstances?
